Does tea-serving follow any special etiquette in China ? Each time I dropped in at my Chinese friends ' homes , their parents would offer me a cup of hot , strong tea , though they never inquired of me about whether I want it . 
 You've got a point there . It is a custom and good manners to serve tea to a guest who comes to pay a visit . There is no need to ask if he needs it or not , or if he wants something else . It might be an insult to the guest if he is left sitting there without being served tea .
